[RFC] gitweb test script

[Matthias Lederhofer <matled@xxxxxxx>]

Perhaps this script has a place in the git repository.  Creating some automated
tests at least checking for warnings should be easy too.  This should work from
the git repository and makes gitweb use .git as repository.  At the moment it
still needs the git binary to be in the path already to find the top repository
directory.

This could also be extended for automated tests.  Here is an example how this
could look like (currently this does not test much of gitweb):

#!/bin/sh
die() {
	echo "$0: $*" >&2
	exit 1
}

cleanup() {
	[ -e "$TMP" ] && rm "$TMP"
}

test() {
	echo "test: $@"
	"$gitweb" "$@" > /dev/null 2> "$TMP"
	if [ ! -s "$TMP" ]; then
		return
	fi
	echo "========== ERRORS =========="
	cat "$TMP"
	echo "============================"
}

gitweb="./`git rev-parse --show-cdup`/t/gitweb.sh"
TMP=""
trap cleanup EXIT
TMP="`mktemp`" || die mktemp failed
